CO₂ Storage: A Key Component in Climate Action
In response to the urgent need for global emission reduction, CO₂ storage has become an important means to address climate change. For enterprises in the field of low-temperature gas equipment, mastering this technology not only concerns their competitiveness, but also represents a significant opportunity to participate in the transformation of the sustainable economy.
What is CO₂ storage?
CO₂ storage refers to the process of capturing carbon dioxide emitted by industries or existing in the atmosphere and safely storing it to prevent its release into the atmosphere. It is the core component of the carbon capture, utilization, and storage (CCUS) system, helping to achieve the goal of carbon neutrality.
Main storage method
Geological storage
Injecting CO₂ into deep underground rock formations, including depleted oil and gas fields, saline aquifers, and unextractable coal seams, to utilize their pore structures for long-term storage.
Ocean storage
This method involves sequestering the substance by dissolving it in seawater or depositing it on the deep-sea floor. It is still in the experimental stage and the ecological impact needs to be evaluated.
Biological storage
By relying on natural systems such as forests and soil to sequester carbon, methods like afforestation and ecological agriculture offer low costs and multiple environmental benefits.
Implementation Process
Capture: Extract CO₂ from emission sources or the air.
Compression and Transportation: Pressurize it to a liquid or supercritical state and transport it via pipelines or ships.
Injection: Inject it into underground reservoirs through deep wells.
Monitoring: Use technologies such as seismic imaging and sensors to ensure the safety of storage.
The role of low-temperature equipment enterprises
Low-temperature gas equipment, such as compressors, storage tanks, valves, and monitoring systems, is widely used for the high-pressure and low-temperature treatment of CO2 in the processes of compression, storage, transportation, and injection. These components are essential for guaranteeing the system’s effective operation.
Future Outlook
The International Energy Agency predicts that CCUS could contribute approximately 14% of the emission reduction needed to achieve the net-zero target by 2050. Despite challenges such as costs, public acceptance, and regulatory development, with technological advancements and the promotion of large-scale implementation, the prospects for CO₂ storage are promising.
